Local library can save you years and tons of money.

My high school has a marine biology/marine studies class. You need physics, chemistry and regular biology and math

You won't really get a choice of what classes to focus in in high school, there's a set curriculum you'll have to follow. Just make sure you do well in any science classes. You won't start taking more marine biology related classes until college.

Usually in year 7 you can't choose any subjects. In year 8, biology isn't a choice. I think you have to wait until year 10 to take biology. Just ask a teacher at the high school you plan on going to or check out their website.
